I performed the BCA assay to calculate protein content over the time period. However, I'm not understanding how I can calculate the degradation rate in percentage at each time point? What formula I have to apply to calculate degradation rate?
You need to calculate the degradation rate always in relation to its initial concentration:
Degradation Rate = (Co- Ct) / Co
or Co is the concentration a to
and Ct the concentration at the moment t
To get the percentage, multiply to 100. Note that you must always calculate the concentration at different times in relation to its INITIAL concentration.
